in this Project my rule is Head of the technical office and my Tasks and Achievements as:

*Design and calculation of the Excavation structure of the type of Braced Cut and anchorage in the -23 meter Excavation
*Project control and work scheduling

*meter and estimation of materials and manpower
*Welding control and workshop reports
*Optimizing the design using ST52 sections and Reduce 40% Weight of Structure

Implementation of flange connection in middle struts Dealing with the status of contractors 

In the design of Braced Cut system, the following items are checked and then according to the mentioned items, the required type of system and sections are selected and designed. These include:

Geotechnical studies of the project (layering and selection of physical and mechanical parameters of each layer)

Groundwater conditions

Determining Live loads (material depot and workshop equipment, etc.) or Dead loads (buildings, etc.) adjacent the pit

Determining the depth of the pit walls based on the topographic conditions and the foundation level of adjacent buildings

Evaluation of adjacent structure sensitivity to the amount of deformation

Component arrangement of the Braced Cut system, considering guard structure and main structure interferences and the maneuverability of the machines

Type the design based on the above six items

Selecting appropriate geotechnical and structural software for modeling

Review and select related Code

Economic considerations
